A Black Friday Snooze Fest: Massive Traffic, No Drama
Blog post from Sanity
Sanity's introduction of the Live Content infrastructure and High-Frequency CDN has revolutionized content management during high-volume commerce events by effectively handling massive traffic while enabling rapid content updates. This system addresses the tension between caching for efficiency and the need for immediate cache invalidation to accommodate time-sensitive changes, such as expiring offers or out-of-stock product promotions. The infrastructure's success was highlighted during Black Friday 2024, where Sanity's customers experienced seamless functionality without the typical disruptions associated with high-traffic events, achieving a service success rate of 99.999205% over 8 billion requests. This landmark performance demonstrated that with advanced CDN technology, major e-commerce events can become "non-events," characterized by uninterrupted service and enhanced customer satisfaction. Sanity aims to normalize this standard of excellence in future high-traffic scenarios.
